MasterRoc SA 167
Alkali-free, liquid high-performance set accelerator for sprayed concrete
How does MasterRoc SA 167 work?
MasterRoc SA 167 is a high performance, alkali-free shotcrete accelerator designed for use in the wet-mix shotcrete application process. This liquid admixture allows adjustable dosage to achieve the desired setting and hardening times, offering flexibility in various applications.
Recommended uses:
Temporary and permanent ground support in tunneling and mining operations
Acceleration of cementitious grouts, such as annulus grout in TBM tunneling, cement grout for injections, and cellular concrete for backfill operations
Slope stabilization
Other concrete or cementitious grout applications requiring high early strength, high final strength, and thick layer application in a single process
What are the unique features of MasterRoc SA 167?
Fast-setting properties
Continuous strength development at both early and later stages
Low dust generation and minimal rebound during shotcrete application
Non-aggressive composition
Alkali-free and chloride-free formulation
Ability to construct thick sprayed concrete linings via layered application during one construction sequence
